This is the moment a `spoiled brat` appeared to launch into a vile foul-mouthed rant at a man thought to be her granddad - because they were a few minutes late for an iphone appointment.

In the video the green-haired youngster screams: I dont want to wait in line for 20 f*****g minutes doing absolutely nothing when were supposed to be at our f*****g appointment.

It all kicks off because the pair are apparently just a few minutes late for a Genius Bar appointment to fix the girls broken phone.

The moody girl appears to burst into tears during the whinging meltdown in the middle of a shopping mall as she claims to be starving and demands cash for food.

She screams: "Can you please just go up there and talk to them for me and like leave me the money or something.

You take my phone and you go up there and you talk to them and yeah."

Her embarrassed `granddad` then appears to hand over his credit card and takes the iPhone to be fixed but her complaining doesnt stop there.

The teen then goes in a strop and stamps her feet on the ground as she shouts what the f***k for all to hear.

Although unclear where and when the footage was taken, it was uploaded to Live Leak today and is thought to be in America.

The person who uploaded the footage added: "I was in a mall waiting for Asian food which ended up tasting like garbage.

"All of a sudden this green haired girl starts cussing at her Grandpa about how they`re going to be late to fix her iPhone.

"Merry Christmas I guess."

The clip has racked up thousands of views and has led to the girl being compared with Veruca Salt  the rich brat from Charlie and the Chocolate Factory who demands: I want the world, I want the whole world.

One commenter said: "I would have walked up to her face mid rant, during her startled pause from my invasion of her safe space, I would loudly say You are an ugly crier, then smile and walk away."
